THlLL-COUPLING.

SPECIFICATION forming part 0f Letters Patent No. 432,064, dated July 15,1890.

Application filed May 2| 1890. Serial No. 350,345. (No model.)

To all whom zit may concern:

Be it known that I, HENRY F. MCKNIGHT, a citizen of the United States,residing at Ingraham, in the county of Clay and State of Illinois, haveinvented a new and useful Thill- Coupling, of which the following is aspecification.

The invention relates to improvements in thill-couplings andanti-rattlers.

The object of the present invention is to providea simple andinexpensive thill-coupling which is capable of ready adjustment todifferent-sized thill-irons, and in which the Wear can be readily takenup, and which will prevent noise and rattling and dispense with springsand rubbers usually employed to accomplish this result.

The invention consists in the construction and novel combination andarrangement of parts, hereinafter described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective View of a thill-couplingconstructed in accordance with this invention. Fig. 2isa verticaltransverse sectional view. Fig. 3 is a horizontal sectional view. Fig. 4is a detail view of the clip.l Fig. 5 is a similar view of one of thebearing-blocks.

Referring to the accompanying drawings, l designates an axle-clip of theordinary construction, provided at its front end with alaterally-projecting plate 2, formed integral with the clip, and provided with acountersunk slot 3 and a countersunk opening 4, arranged upon oppositesides of the clip-,arm to receive bolts 5 and 6 to secure it to the clipbearingblocks 7. The countersunk slot 3 enables the bolt and itsbearing-block to be adjusted laterally to adapt the coupling toany-sized thill-iron, and the bolt 6 may, if desired, be

formed integral with the plate of the clip;

but it is found preferable to construct it as illustrated in theaccompanying drawings. The bearing-blocks 3 are provided with hori-Zontal holes 4, through which pass the bolts 5 and G, the outer ends ofwhich are threaded and adapted to receive nuts 3, to secure thebearing-blocks, and the rear ends of the latter fit squarely against theplate 2 of the clip. 5o The bolts 5 and G are parallel and areartightened to take up Wear and prevent noise and rattling and toregulate the adjustment of the laterally-sliding bolt.

It will readily be seen that the thill-coupling and anti-rattler issimple and inexpensive in construction and is adapted to take up thewear of the parts and dispenses with the springs, rubbers, and the likeusually employed in an anti-rattler. i

Vhat I claim is- 1. In a thill-coupling, the combination of the clip,the bolts projecting forwardly therefrom and arranged at each side ofthe same, the bearing-blocks secured upon the bolts and provided withbearing-openings, and the thill iron arranged between the bearingblocksand secured thereto by a couplingbolt, substantially as described.

2. In a thill-coupling, the combination of the clip having the integralplate 2, provided with bolt-openings, the bolts arranged in saidopenings and projecting forwardly from the clip, the bearing-blocksprovided with horizontal openings to receive the bolts and havingcountersunk bearing-openings, the thilliron having its eye oppositelybeveled and arranged in the countersunk bearing-opening, and thecoupling-bolt, substantially as described.

3. In a thill-coupling, the combination of the clip having the plate 2formed integral therewith, and provided with the countersunk slot 3 andthe countersunk opening 4, the bolts 5 and 6, arranged in the slot andthe opening, the bearing-block fitting squarely my own I have heretoafxed my signature in against the plate 2 and provided with horipresenceof two Witnesses. f zontal holes 4 t0 receive the bolts, and havingeountersunk bearing-openings, the thill- HENRY F.

In testimony that I claim the foregoing as JACOB D. SHADLE.
